Acquisition Acquisition concepts Acquisition hardware Before a signal is displayed, it must pass through the input channel where it is scaled and digitized. Each channel has a dedicated input amplifier and digitizer. Each channel produces a stream of digital data from which the instrument extracts waveform records. Sampling process Acquisition is the process of sampling an analog signal, converting it into digital data, and assembling it into a waveform record, which is then stored in acquisition memory.
Page 69
Acquisition Real-time sampling In real-time sampling, the instrument digitizes all of the points it acquires using one trigger event. Use real-time sampling to capture single-shot or transient events. Interpolated real-time sampling In interpolated real-time sampling, the instrument digitizes all of the points it acquires using one trigger event. If the instrument cannot acquire enough samples for a complete waveform at the maximum real-time sample rate, it interpolates.
Page 70
Acquisition Interpolation Your instrument can interpolate between the samples it acquires when it does not have all of the actual samples it needs to fill the waveform record. Linear interpolation computes record points between actual acquired samples by using a straight line fit. Sin(x)/x interpolation computes record points using a curve fit between the actual values acquired.
Page 71
Acquisition Acquisition mode Waveform Database mode is a three-dimensional accumulation of source waveform data over several acquisitions. In addition to amplitude and timing information, the database includes a count of the number of times a specific waveform point (time and amplitude) was acquired.

Acquisition Selecting the horizontal mode Your instrument has three horizontal modes. Automatic is the default mode. Select the horizontal mode that works best for your test setup. To set the horizontal mode, select Horiz/Acq > Horizontal/Acquisition Setup to display the horizontal control window. Choose one of the modes described below.
Page 74
Acquisition In Manual mode you can set the Sample Rate and Record Length. Horizontal Scale is a dependent variable calculated from the sample rate and record length. The Horizontal Scale knob changes record length in manual mode. All three modes interact with sample rate, scale, and record length as shown. The horizontal line is the maximum real-time sample rate. Each staircase shows that as you increase the scale, the sample rate must decrease when either the maximum record length or the record length limit you set is reached.

Pinpoint triggers Pinpoint triggers The Pinpoint trigger system comes with advanced trigger types that are usable on both A and B triggers, and it can reset the trigger sequence if the B event does not occur after a specific number of events or a specific time. Pinpoint triggers support capture of events based on the most complex trigger event or sequence of trigger events.

Pinpoint triggers Horizontal position Horizontal position defines where the trigger occurs on the waveform record. It lets you choose how much the instrument acquires before and after the trigger event. The part of the record that occurs before the trigger is the pretrigger part. The part that occurs after the trigger is the posttrigger part.

Analyzing waveforms Analyzing waveforms Your instrument features cursors, automatic measurements, statistics, histograms, math, spectral analysis, and advanced pass/fail tests to help you to analyze waveforms. This section contains concepts and procedures for analyzing waveforms. Detailed information is available in the online help. Taking automatic measurements 1.
Page 132
Analyzing waveforms Quick tips • In roll mode, measurements are not available until after you stop the acquisition. WARNING: If there is vertical clipping, there may be a dangerous voltage on the probe tip, but the readout will indicate a low voltage.
Page 133
Analyzing waveforms Measurement Description The most positive peak voltage. Max is measured over the entire waveform or gated region. The most negative peak voltage. Min is measured over the entire waveform or gated region. Pk-Pk The absolute difference between the maximum and minimum amplitude in the entire waveform or gated region.
Page 134
Analyzing waveforms Measurement Description Cycle Area The area over the first cycle in the waveform or the first cycle in the gated region expressed in volt-seconds. The area above the common reference point is positive while the area below the common reference point is negative.

Analyzing waveforms Using mask testing Serial Communications Mask Testing (Option MTM or MTH) allows you to compare your signal to a predefined template or mask. For the signal to pass the test, it must fall outside the segments defined by the mask. Generally, standards committees such as ANSI define the masks.
